6.1.C. - Page 9 <br /> EXHIBIT A <br /> PROJECT SCOPE OF WORK,DELIVERABLES,DEADLINE <br /> AND PAYMENT TERMS <br /> Description <br /> Closed circuit television(CCTV)inspection,and cleaning for that purpose,of selected pipelines in <br /> sanitary sewer basins 5G and DT2. <br /> SCOPE OF WORK: <br /> The scope of work described herein is the minimum necessary to meet the City's objectives. The <br /> CONTRACTOR is expected to expand on the scope by incorporating their expertise and proposed <br /> method of approach. <br /> The scope of work for the project shall include the furnishing of all labor, materials, and equipment <br /> necessary to clean the sewer pipelines, inspect manholes and provide a closed- circuit television <br /> inspection in digital format of the sewer pipelines listed above. The word "clean" is defined as the <br /> removal of all accumulations including sludge, dirt, sand, rocks, grease, roots, and other solid or <br /> semisolid material in the pipe and manhole. <br /> Cleaning <br /> The CONTRACTOR shall perform a minimum of two (2) passes using the high-velocity hydraulic <br /> cleaning method. The contractor shall clean the Iine until the line is ready for closed-circuit television <br /> inspection that's acceptable to City.No additional compensation will be made to the CONTRACTOR in <br /> performing three or more passes in cleaning the sewer line.All pipe cleaning cost method and duration <br /> shall be included in the agreed cost irrespective of the type and size of the existing sewer lines. If a video <br /> and/or the capture images in the database do not clearly show the pipe conditions due to inadequate clean- <br /> up or are of such poor quality that the Engineer is unable to evaluate the condition of the sewer or locate <br /> sewer service connections, the CONTRACTOR shall re-televise that section of the pipe at <br /> CONTRACTOR'S expense. <br /> The CONTRACTOR shall protect the manholes to withstand forces generated by equipment,water, and <br /> air pressure.The CONTRACTOR shall clean the sewer pipe of any obstruction and debris including roots <br /> in accordance with the "Standard Specifications for Public Works Construction (Green book)", latest <br /> edition. <br /> CONTRACTOR shall use a jet/vacuum combination unit for cleaning all sewer lines. The combination <br /> unit shall operate at 80 gallons per minute at a pressure of 2,500 psi,and be equipped with approximately <br /> 800 linear feet of hose. CONTRACTOR' S operating technicians shall have a minimum of 3 years of <br /> experience cleaning with this piece of equipment.CONTRACTOR shall clean the lines in a downstream <br /> direction,beginning from the most upstream manhole of a particular reach or set of reaches, and begin <br /> cleaning so that the debris will continually be pulled downstream. <br /> In order to jet clean the lines, a high pressure water pump on the combination truck shall deliver water <br /> from attached tanks through a high pressure hose to a cleaning nozzle. The water pumped through the <br /> cleaning nozzle shall propel the nozzle and attached high pressure hose through the sewer. Once the <br /> cleaning nozzle has arrived at an upstream manhole,the nozzle shall be pulled back through the pipe at a <br /> velocity controlled by the operator. During the cleaning process,the cleaning nozzle will not travel faster <br /> REV:03-16-16 VR <br /> Page 6 of 12 <br /> ATTY/AGR.2016.052/Professional Pipe Services <br />
